Answer:
$11.13
Step-by-step explanation:
$7.00 + $3.50 = $10.50
6% of $10.50 is $0.63
$10.50 + 0.63 = $11.13
Answer: The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
Let x represent the number of 3-point questions.
Let y represent the number of 5-point questions.
The maths test consists of 24 questions. This means that
x + y = 24
Each question is worth either 3 points or 5 and the test is worth 100 points. This means that
3x + 5y = 100 - - - - - - - - - - -1
Substituting x = 24 - y into equation 1, it becomes
3(24 - y) + 5y = 100
72 - 3y + 5y = 100
- 3y + 5y = 100 - 72
2y = 28
y = 28/2 = 14
Substituting y = 14 into x = 24 - y , it becomes
x = 24 - 14 = 10
Answer:
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality
Round and then see what the number you have too add, subtract , multiply, and divide and then you would find the answer
Answer:
-2.5
Step-by-step explanation:
We need to find the slope using and two points
m = ( y2 -y2)/(x2-x1)
= ( 25-20)/(-10 - -8)
= 5/( -10+8)
= 5/-2
- 2.5
